FOUNTAIN-PEN.

SPECIFICATION forming part of Letters Patent No. 766,760, dated August2, 1904.

Application filed February 2, 1904. Serial No. 191,702. (No model.)

To all, ux/wm, it may concern:

Be it known that I, ALFRED B. DAvIs, a citi- Zen of the United States,residing' in Philadelphia, Pennsylvania, have invented certainImprovements in Fountain-Pens, of which the following is aspecification.

My invention consists of an improved fountain-pen of the class providedwith iillingpistons, the object of the invention being to provide a penof the class noted which shall be of sim pleand inexpensive constructionand elicient in operation.

It is further desired to provide a pen of such construction thatit willnot be liable to get out of order or to become inoperative by reason ofthe thickening of the ink used and one that can be cleaned by drawing inand ejecting water without removing' the pen or feeder.

Another object of the invention is to provide a fountain-pen having' afeeder of improved construction.

These objects I attain as hereinafter set forth, reference being had tothe accompanying' drawings, in whichw Figure l is a sectional elevationof my improved pen, showing the detail construction of its parts. Fig. 2is a side elevation of my improved feeder. Eigs. 3 andet arerespectively a plan view and an end elevation of the feeder shown inFigs. l and 2, and Fig. 5 is an enlarged sectional elevation showing thedetail construction of a part of my invention.

In the above drawings, A is a tubular section, usually formed of hardrubber or other suitable material and closed at one end. Entering theopen end of said section is a body or pen-carrying section B, which isalso tubular and open at that end which enters the said body portion. Inits opposite end is fitted a piece C, which serves the double functionof plug for said end and feeder fora pen c,'which is confined between itand the end of the said section B. The open end of the section A isprovided with an inwardly-extending ange a, while the adjacent end b' ofthe body-section B is enlarged and provided with annular grooves whichare preferably filled with some form of material, such as a solidlubricant or body of packing. This construction of the parts A and Bprevents the withdrawal of one from the other.

The feeder C is of such a cross-section that it closes the end of thebody-section B, with the exception of two relatively contracted openingson cach side of its central longitudinal rib e. This rib engages theunder side of and extends parallel with the pen c, and the body of thefeeder C is so cut away as to form the above-mentioned openings, whichincrease in area of cross-section from the point of the pen inwardly. Itwill thus be seen that ink liowing tothe pen passes out through channelsformed on either side of the rib c of the feeder and is directed in twostreams to the under side and point of the pen. Said feeder ispreferably made of soft rubber, since this is the only material whichcan be used to close the end of the tubular section with sufficienttightness without pressing' so hard on the pen as to spread the nibsthereof. Furthermore, by reason of the material of the feeder followingthe nibs of the pen as they are bent in the action of writing there iscaused a pumping action which insures a constant flow of ink to the pen.

V hen it is desired to till the device with ink, the section A and thebody-section B are first collapsed or pushed together as far aspossible, after which the pen is inserted in a reservoir containing ink,and the body portion is slowly pulled out of the pen-carrying section.This action causes ink to be drawn into the interior of the pen, afterwhich said pen is ready for use.

lVhcn it is desired to clean the device, the pen and feeder can bepulled out of the bodysection B, thus giving access to the interior ofthe pen and permitting quick removal of any hard or gurnmy materialwhich may have collected, or, if desired, water can be drawn in andejected to cleanse the feed and pen.

In Fig. l I have shown in dotted lines a cap or cover D, which is oflength sufficient to lit over the body-section and to frictionallyengage the end of the section A even when said section B is in itsfully-extended position. When the pen is in use, this cap fits over andfrictionally engages the rear of the section A, Y

it being understood that this latter is suitably adapted for threception of said cap.

I claim as my invention 1. Afountain-pen having a tubular section, a penin the end thereof and a feeder of relatively resilient material forsaid pen, said feeder being of a substantially circular section andhaving longitudinal grooves on either side of it, substantially asdescribed.

2. The combination in a fountain-pen of a tubular section having a pen,a feeder therefor of soft, relatively elastic material fitting into thefront end of said tubular section, said feeder being groovedlongitudinally so as to form a rib, said rib being in contact With underside of the pen, substantially as described.

3. The combination in a fountain-pen of a tubular section having' in oneend a pen with a feeder therefor, the feeder having grooves decreasingin area of cross-section as they approach the point of the pen, saidfeeder otherwise filling the end of the tube, substantially asdescribed.

4. The combination of a tubular section having in one end a pen and afeeder of soft, relatively elastic material, there being grooves in saidfeeder extending adjacent to the pen, and

so placed as to form a rib in contact with the under side of the pen,substantially as described.

5. The combination in. a fountain-pen of a tubular section having' inone end a metallic pen and afeeder therefor of soft rubber, said feederhaving longitudinal grooves placed to form a rib, said rib being incontact With the under side of the pen, substantially as described. 6.The combination in a fountain-pen of a tubular reservoir having in oneend an opening, a pen and a feeder in said opening, said feeder having alongitudinally-extending rib portion in contact with the pen, therebeing a channel in the feeder on each side of Said rib, substantially asdescribed.

7. The combination with a tubular reservoir of a pen and a feedertherefor of com pressible material, there being a conduit for ink insaid feeder, the. same being placed to deliver ink to the under side ofthe pen, substantially as described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing Witnesses.

ALFRED B. DAVIS.
